You could use UIWebView to view the pdf file.

Check the below SO post.

@Jhaliya.How to give scroll view for scrolling pdf files. Thanks great update. – Ajay_Kumar Jun 06 '11 at 11:03
@Ajay_Kumar : `UIWebView` will take care of that because it's inherited from `UIScrollView`. – Jhaliya - Praveen Sharma Jun 06 '11 at 11:04
I wrote code for fetching pdf file. I added that pdf in my resource directory of project. NSURL *targetURL = [NSURL URLWithString:@"Chapter01Page01.pdf"]; – Ajay_Kumar Jun 06 '11 at 11:11
Is it write ? I am not seeing pdf file is appearing on screen. – Ajay_Kumar Jun 06 '11 at 11:11
Use a UIDocumentInteractionController instead for the default pinch zoom and scrolling behaviour that iOS uses by default for documents etc. – Luke Jun 06 '11 at 11:12
@Ajay_Kumar : Have you added **webview** object as **subview** in your main view ? – Jhaliya - Praveen Sharma Jun 06 '11 at 11:18
@Jhaliya. I have written [self.view addSubview:webView]; [webView release]; And i also added one webview in view from builder. And also why this is not reading my local file which is kept in resiurce directory. – Ajay_Kumar Jun 06 '11 at 11:24
This is loading pdf file, if i am giving URL pat as per above link. But scroll is not vertical scroll is not coming. I am seeing horizantal scroll. And also kindly know me how to read local file, which is kept in my project->resource->directory. – Ajay_Kumar Jun 06 '11 at 11:27
@Ajay_Kumar : i think you have'nt given the correct file path. – Jhaliya - Praveen Sharma Jun 06 '11 at 11:31

Here's how you can read and store your pdf locally:

First create UIWebView and include <<UIWebViewDelegate>>

  NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
  NSString *documentsPath = [paths objectAtIndex:0];
  NSString *filePath = [documentsPath stringByAppendingPathComponent:@"YourPDF.pdf"]; 
 if(![[NSFileManager defaultManager] fileExistsAtPath:filePath]){
           // download file , here "https://s3.amazonaws.com/hgjgj.pdf" = pdf downloading link
         NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"https://s3.amazonaws.com/hgjgj.pdf"]];
            //Store the downloaded file  in documents directory as a NSData format
         [pdfData writeToFile:filePath atomically:YES];
    }

     NSURL *url = [NSURL fileURLWithPath:filePath];
     NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
     [yourWebView setUserInteractionEnabled:YES];
     [yourWebView setDelegate:self];
     yourWebView.scalesPageToFit = YES;
     [yourWebView loadRequest:requestObj];

Or, if you simply want to read/load pdf from your Resource folder then simply do this :

     NSString*  filePath= [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"pdf"]];
    /// or you can even read docs file as : pathForResource:@"sample" ofType:@"docx"]
     NSURL *url = [NSURL fileURLWithPath:filePath];
     NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
     [yourWebView setUserInteractionEnabled:YES];
     [yourWebView setDelegate:self];
     yourWebView.scalesPageToFit = YES;
     [yourWebView loadRequest:requestObj];
